Feature: 1. It is made of premium material, silicone covered design, antislip and antidrop, wear resistance and with comfortable grip feeling. 2. Adopts a quality counting tube with high detection sensitivity, especially for environmental radioactivity monitoring to detect traces of nuclear radiation and electromagnetic radiation. 3. Configured LCD color screen, with multifunctional monitoring pages, real-time display of current dose rate real-time value, cumulative measured value, cumulative stored dose rate, maximum value, average value, starting date, cumulative time. 4. The detector is used to measure X, γ and β rays radiation, it is optimal for measuring small changes in radiation levels, and has high sensitivity for most commonly used nuclides. 5. Three alarm modes design, with sound/light/vibrating alarm when dose rate and cumulative dose are over threshold, and the thresholds of dose rate and cumulative dose can be set manually. 6. Wide applications, suitable for family decoration, hygiene, radiation treatments, nuclear lab, nuclear station, import-and-export commerce inspection, building materials, petroleum chemical, geology general investigation, used steels, industry flaw detection and others.
